Now this is interesting

Apparently there is growing evidence that state attorneys general have illegally conspired with each other, and with environmental groups, in attempting to prosecute lawsuits against fossil fuel producers and users who have funded research critical of the global warming hypothesis.

Interesting, and ironic, since their behavior falls into the same legal bin that they're trying to use to prosecute fossil fuel producers--RICO.  Moreover, unlike the work of fossil fuel producers and users, there appears to be an abundance of evidence to prove the case.

Throw the book at them.   We need robust debate before implementing actions to deal with climate change, not intimidation tactics.
